It have only one queue and two consumers of same queue. The consumers do<br>
nothing - only sleep 1 second in 100 threads generated by pool,<br>

So that would give you a maximum rate of 200Hz, which is not that far off the rate you are seeing in the management UI. The difference will be accounted for by network latency, *especially* if you are using basic.qos with a low prefetch count.<br>
